Upton was finally healthy for an entire season in 2011, and met all the lofty expectations placed on him in the second year of a six-year, $51.25 million contract signed when he was 22. He set career highs in homers (31), RBI (88) and stolen bases (21, caught nine times), while compiling a .289/.369/.529 line. Through their age-23 season, there have been only four others to match Upton’s 91 homers, 62 stolen bases and 119 OPS+: Alex Rodriguez, Jose Canseco, Ken Griffey Jr. and Orlando Cepeda. Pretty elite company, and Upton still has time to mature as a player and team leader. I’m looking forward to watching this multifaceted young man do his thing again in 2012. -- Diane Firstman, Value Over Replacement Grit

A healthy Heyward has to be the player Braves fans are most excited to see this season. Through injuries, bad habits developed while playing injured and benchings, just about everything that could have gone wrong for such a talent did go wrong last year. Despite all of that, Heyward never hung his head or complained and actually managed to produce slightly above-league-average value in right field. Heyward has reportedly straightened his swing out this offseason and has really worked hard to get his game back on track. If Heyward can get a little more elevation on his swing, while maintaining the other aspects of his rookie performance, Braves fans could once again witness a once-in-a-generation talent leading the team to a successful season. -- Franklin Rabon, Capitol Avenue Club

In 2010, Wood made his big league debut for the Reds in an outing against the Cubs. He was brought in this offseason as part of the deal that sent Sean Marshall packing. For some, that was a disappointment considering Wood’s ERA last year was 4.84, but if we look beyond that we see that Wood posted a FIP ERA of 4.06, and Bill James projects him for an ERA of 3.75 in 2012. Also factor in that Great American Ballpark is a tough place to pitch; Wood had a 5.30 in the Gap vs. 3.58 on the road. Wrigley is not the hitters’ park we’ve all been told it is, primarily due to the wind blowing in often early in the year. The move from Cincinnati should do a lot toward boosting Wood’s production and confidence. -- Joe Aiello, View From the Bleachers

Anticipation is building steadily for Latos' debut in a Cincinnati uniform. At 24 years of age and with a couple of excellent seasons already under his belt, the sky is the limit for him. For Reds fans, there is the hope that the club will have a legitimate ace at the top of the rotation for the first time in a couple of decades. Yes, there is reason for legitimate excitement in the Queen City. -- Chad Dotson, Redleg Nation

It’s a debate in my mind between Tulowitzki and Carlos Gonzalez. Both have tremendous gloves, bats and arms. Tulo trained this offseason with Jason Giambi in Las Vegas, and one could extrapolate some motivation from Dan O'Dowd's offseason acquisitions and trades. (O'Dowd believes the team needs leaders and better clubhouse guys, so what does that say about Tulo who plays the most important position on the field, is signed through 2020 and the face of the franchise?). What will Tulo do this year? I think 30 homers, Gold Glove-level defense and solidifying his place as the best player in baseball is a sure bet. Are the playoffs a sure bet for the Rockies? MVP for Tulo? I can't wait to see! -- Travis Lay, Blake Street Bulletin

With all of the changes, everyone seems to have forgotten that Lyles was recently the Astros’ top prospect. How quickly a young player that showed real promise last year has become overlooked in Houston. He's only 21 years old and had a number of very promising starts last year, posting a fair 4.41 ERA through July before running out of gas and getting shelled in August and September. He clearly needs to continue to build his stamina and strengthen himself to last the entire season. I'm interested to see how he continues to progress and if we can see him grow into the kind of player that can withstand the rigors of an entire major league season. I don't know how the Astros faithful have forgotten about Lyles so fast, but I think they'll be quickly and pleasantly reminded why he was considered a top prospect. -- Austin Swafford, Austin’s Astros 290 Blog

Heaven knows it's hard not to be excited about the return of Juan Uribe or the potential of having Juan Rivera for a full season. But even so, there's a small, small part of me that is intrigued by these fellas named Matt Kemp and Clayton Kershaw. They made a bit of an impression last year, and I can't say I'm not going to be, well ... OK, hanging on their every swing and pitch. But to avoid being too reliant on last year's stars, the new Dodger Roadrunner, Dee Gordon, will also be an exciting player to watch. -- Jon Weisman, Dodger Thoughts

The player I'm truly most excited to see don a Marlins uniform this season is Logan Morrison. Following a splendid sophomore season in 2011, Morrison enters the new season as one of the game's top outfielders in the National League. With a solid approach and some power, a full season from Morrison could result in at least five additional wins for the Fish -- assuming Morrison can remain healthy. -- David Gershman, Marlins Daily

Last season, the Brewers didn't even get to see their prized acquisition participate in spring training, as Greinke broke a rib playing pickup basketball and missed all of spring and the first month of the season. This season, no basketball for the former Cy Young award winner. He'll be there through spring training and Brewer fans hope to avoid the slow start he suffered through last season. Greinke posted just a 5.63 ERA despite an 80:12 K:BB ratio in May and June last season (mostly thanks to eight home runs) before calming down in the second half. Greinke finished strong, posting a 2.80 ERA thanks to a .233/.293/.373 line allowed in July, August and September. -- Jack Moore, Disciples of Uecker

After a winter of discontent for Mets fans, it’s hard to be excited about anyone in particular. The team is in desperate financial straits, is slashing payroll at record rates, and appears destined to finish in last place. Wright, the one player for whom I reserve excitement, may not even be on the team after July 31. Still, I’m highly anticipating his 2012 performance, because after two disappointing seasons I’m convinced that Wright has too much pride to have a third. For the first time in his career, the Mets are “his” team -- he’s the de facto leader, the man who sets the example for everyone else. Chances are, Wright is determined to have a career year, and will pound opposing pitching with a savage vengeance -- all in the name of leading the Mets to a less-than-90-loss season. -- Joe Janish, Mets Today

It was easy to be impressed by the sustained excellence of Atlanta's Jonny Venters last season, but Bastardo was quietly in the same neighborhood. Bastardo had a monster 2011 in which he struck out nearly 11 batters per nine innings and held opponents to a .524 OPS. If he can even approach his 2011 performance, Bastardo, along with Jonathan Papelbon and the Phillies' army of young guys who throw hard (Mike Stutes, Justin De Fratus, David Herndon and so on), gives the Phillies' bullpen the potential to be one of the best in the National League. -- Michael Baumann, Crashburn Alley

While Andrew McCutchen remains eminently exciting, we have a firm grasp on his star-level capabilities. I’m more excited to see whether Alvarez can rebound from his terrible sophomore season and get back to where his debut left off. The Pirates have a chance at a bright future, but all of their elite prospects are several years away. If there is any hope to be a competitive team in 2012, Alvarez has to give McCutchen and Neil Walker some help offensively. He has barely played a full season of games (169), and there is still time for him to meet the expectations that come as a No. 2 overall pick. Hey, Alex Gordon finally did. -- Paul Sporer, Pitt Plank

Despite losing everyone's perennial favorite player to watch to free agency, the defending champs have several captivating players in 2012. Partly because fans haven't seen him in a year and partly because he throws one of the most entertaining curveballs in the game, Wainwright will be a sight for sore eyes as he comes back from Tommy John surgery. But the player with whom Wainwright will forever be linked in fans' memories, Carlos Beltran, also figures to be a pivotal and exciting addition to the post-Pujols roster. -- Matt Philip, Fungoes

The acquisition of Quentin brings energy, excitement and more total bases (210 in 2011 with the White Sox) and home runs (24) than any Padres player had last year. The Padres now employ two hitting coaches -- a model just a few MLB teams use -- as Phil Plantier and Alonzo Powell help with the workload hitting instruction requires. Quentin plays hard and he will help change the dynamics in the clubhouse. With the Padres' deep farm system and strong pitching, Quentin just might be the player to add the much needed spark of power in the middle of the order. -- Anna McDonald

I think I can speak for Giants fans everywhere when I say the player that I'm most excited to see play this season is Posey, and it's not even close. His injury in 2011 was a black mark on a year that we'd all like to forget. Beyond the numbers, Posey has quickly become the face of the Giants. He's young, energetic, talented and -- for us fans -- we hope healthy. Regardless of what happens, I'll be happy to see him back on the field in 2012. -- Chris Quick, Bay City Ball

How could it be anyone but Strasburg? When healthy, the most hyped pitching prospect in over a decade has delivered some fabulous pitching performances, and yet it feels like he is just scratching the surface of what he can do. He's as equally likely to blow guys away for a double-digit K performance as he is to shut a team down and let just two guys reach first over eight innings. He looked so good at the end of last year that the feeling is the only thing that can stop him in 2012 are the limits imposed by his own team to protect his recovering arm. -- Harper Gordek, Nationals Baseball
